hatcher!) , tuffs, and Neocene sandstones and conglomerates. Im- 

 mediately about the town there are several outcrops of tuff. 



Hamilton and Tchihatcheff report the same types as making 

 the entire region west to near the Delidje Yrmak, and northeast 

 for an equal distance. To the southwest, however, after about 

 ten miles they gradually give place to neocenes, which extend in 

 the main to Hadji Bektash. Tchihatcheff discusses this complex 

 with the dolerites. 



Getchi Kalesi, the mountain to the east of Medjidie, in the 

 northern part of the Malya Tchol, is only the culminating point 

 in a limestone range, cored with trap, which extends from west 

 of Medjidie southeast for a dozen miles. The limestones at several 

 points contain Eocene nummulites in quantity. At the point 

 where the road traverses this series, south of Medjidie, the eocenes 

 are not conspicuous, and the traps are locally interrupted, but 

 behind the city, the traps stand up in a series of prominent and 

 ragged hills. Even here I have a feeling that the igneous dyke 

 is not entirely continuous. A little farther south, and on the other 

 side of the path, the igneous rocks appear again in a couple of 

 amorphous masses (as seen from a distance), the eocenes remain- 

 ing inconspicuous, but Getchi Kalesi itself is of a somewhat differ- 

 ent structure. The dyke here seems to be fairly continuous, and 

 in general makes the crest of the ridge. Leaning against the west 

 side of this is a long series of Eocene limestones, etc., all with dips 

 of about 6o° to the north. Apparently on the east side of the 

 dyke the same facing occurs, and the very highest point of all is 

 formed by one of these strata which is continuous across the top 

 of the dyke. This very topmost point furnished one of my num- 

 mulite specimens, through the kindness of Mr. Wrench. 



A little farther south the village of Mahmatly is situated in a 

 very striking gorge, which marks the boundary between a lower 

 and a higher level of the Malya Tchol. On the steep sides of this 

 gorge, as well as the escarpments that lead up to its mouth, the 

 neocenes are interrupted, laying bare the substratum of the 

 Tchol, which is evidently of the same system as Getchi Kalesi 

 mountain. Half a day's journey farther south there is a long hill 

 a moderate distance west of the road, which again shows the
